Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement of the flange structure of a vehicle door opening.

<Prior Art> A door in a passenger car or the like is attached to an opening 2 of a vehicle body 1 as shown in FIG. This opening 2
Generally speaking, a four-door car with two doors at the front and rear and a two-door car with only the front door are pointed.Since the size of the doors is different, the position of the center pillar 3 is different, as shown in an enlarged view in FIG.

When installing a door in such an opening 2, it is necessary to prevent water from entering through these gaps. For example, as shown in FIG. A weather strip 10 made of rubber or the like is attached using flanges 4c, 4c' at the upper ends of the panel 4a and outer panel 4b, and a weather strip 13 is also attached around the door 12 for sealing.

<Problem to be solved by the invention> However, since the center pillar 3 is further stacked on the outer panel 4b of the side sill 4, the connection part between the side sill 4 and the center pillar 3 has a different plate thickness from other parts. Since the weather strip 10 does not follow the stepped portion, water may enter the step.

Therefore, as shown in FIG.
b and the outer panel 3b of the center pillar 3
The outer panel 4 of the side sill 4 is aligned with the pillar mounting portion 4d so that the flange 3c is flush with the outer panel 4 of the side sill 4.
A structure is adopted in which the flange 4c' of b and the flange 4c of the inner panel 4a are recessed inside the vehicle body. Reference numeral 3e denotes a support that is connected to the center pillar inner (not shown).

However, this structure is suitable for two-door cars and four-door cars.
If you try to install the center pillar 3 in a different position for a car with a door, the weather strip 5 will not follow the step formed in the recess of the pillar attachment part 4d of the side sill 4 where the center pillar 3 cannot be attached, causing water intrusion. .

For this reason, the side sills 4 constituting the opening 2 had to be manufactured separately, resulting in high cost and complexity. Further, the same thing occurs at the connection portion of the upper end of the center pillar 3 with the roof side rail.

<Means for solving the problems> The purpose of the present invention is to eliminate such conventional drawbacks and provide a flange structure for a vehicle door opening that can prevent water from entering regardless of whether it is a two-door vehicle or a four-door vehicle. shall be. The structure of the present invention to achieve such an object is that in a flange structure of a vehicle door opening in which a weather strip for sealing with the door is attached to the opening flange on the vehicle body side, the flange of the inner panel constituting the opening is a flat plate. On the other hand, it is characterized in that both sides of the pillar attachment part of the flange of the outer panel which is flange-jointed to the flange of the inner panel are gradually expanded to have the same thickness as the pillar.

<Example> Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 5 is a sectional view corresponding to the AA section in FIG. 2 of an embodiment of the flange structure for a vehicle door opening of the present invention.

In the present invention, the flange structure at the connection between the center pillar 5 and the side sill 6 or the connection between the center pillar 5 and the roof side rail is important, and the side sill 6, which is composed of an inner panel 6a and an outer panel 6b, is It is formed by joining flanges 6c and 6d of 6a and 6b. The pillar attachment part 6e of the flange of this side sill 6 is first formed by forming the flange 6c of the inner panel 6a into a flat plate shape, and by forming the flange 6 of the outer panel 6b which is flange-jointed to the inner panel 6a.
d is formed with a recess that becomes a pillar attachment part 6e corresponding to the width of both side flanges 5d of the outer panel 5b of the center pillar 5, and this pillar attachment part 6e is gradually bulged outward toward both sides, and the height of the bulge is That is, the depth of the recess is made equal to the thickness of the center pillar 5.

As shown in FIG. 6, the center pillar 5 has a reinforcement 5c sandwiched between the inner panel 6a and the outer panel 6b of the side sill 6.
a is attached to this reinforcement 5c. Fig. 7 shows the state in which the inner panel 6a is removed from the direction C in Fig. 6, Fig. 8 is a cross section taken along line D-D in Fig. 7, and Fig. 9 is a cross section taken along line E-E in the same figure.

Therefore, when the outer panel 5b of the center pillar 5 is attached to the pillar attachment portion 6e of the flange 6d of the outer panel 6b of the side sill 6, the outer surface of the outer panel 5b becomes a smooth surface connected by a smooth slope.

Therefore, if a weather strip is attached to this flange 6d in the same manner as in the conventional case, there will be no step and the weather strip will run smoothly, thereby preventing water from entering.

On the other hand, in the case of two-door cars and four-door cars, the flange 6c of the inner panel 6a has a flat plate shape and is not molded in any way, so only the outer panel 6b is made to correspond to the respective center pillar positions. It suffices to use only the one in which the pillar attachment part 6e is formed, and the inner panel can be shared.

Although this embodiment has been described with reference to the attachment part at the lower end of the center pillar, it can also be applied to the attachment part at the upper end of the center pillar, that is, the connection part with the roof side rail, and can also be widely applied to the connection parts of other openings.

<Effects of the invention> As explained above in detail along with the examples, according to the invention, only the outer panel is changed to create a flange whose plate thickness changes continuously and smoothly, making it possible to prevent water from entering. At the same time, the cost can be reduced by sharing the inner panel.
